HAYBAKE LOADER.

Application filed. January 19, 1921. Serial No. 438,270.

To all whom it may concern:

Be it known that I, EDWARD MowRY, a citizen of the United States, residing at Rock Falls, in the county of WVhiteside and State of Illinois, have invented certain new and useful Improvements in Hayrake Loaders, of which the following is a full, clear, and exact specification.

This invention relates to hay loaders, and more particularly to those which are adapted to be connected to the rear end of a hay wagon or rack to gather and elevate the hay from the ground to the wagon.

In hay loaders of this type it is not uncommon to arrange the rake bars in groups, and to operate them alternately by rotary means, such as cranks'and the like deriving their power from the ground wheels,

and in order that the rake bars be given the proper motion to effectively perform their raking and elevating function, various devices have been employed to translate or modify the motion imparted by the driving means, such devices cooperating with the respective groups of bars and causing them to pursue, in their reciprocal motions a path of travel most effective for gathering and elevating the hay.

The present invention consists primarily of improved devices for thus translating or modifying the motion imparted to the rake bars by the driving means, such improved devices being characterized by the support of the respective groups of bars near their lower ends on a stationary fulcrum in such a manner that the rotary driving motion imparted by the ground wheels will cause the rake bars to act in a rectilinear line in their raking strokes, so as to properly gather the hay and at the completion of said stroke the rake bars will rise or lift the gathered hay on to the elevator bottom, where it will be subjected to the elevating action of the bars.

It further consists of improved means for balancing the rake carriers in a manner to overcome the jerking of the loader due to the reciprocating movement of the carriers.

The invention consists also of various improved features of construction in the general organization, which features will be fully described in the specification and the novel'parts pointed out in the claims.

In the accompanying drawings:

Fig. 1 is a side elevational view embodying my invention.

Fig. 2 is a rear elevational view of the same.

Fig. 3 is a detail sectional view taken on the line 3-,3 of Fig.1.

Fig. 4 is a 'detail view of one of the carrying wheels and adjacent parts.

Fig. 5 is a detail sectional view ofthe 12. The frame is supported by and secured to standards 13, bars 14: and 15. The standards l3, barsli and15 are connectedto the brackets 16 mounted on the axle 12. Slats 17 are secured together to form suitable bottoms for the conveyor by angle girders 18 and 19. Angles 20 and bar 21 form the sides of the conveyors. An adjustable conveyor section 22 is pivotally connected at 23 -to the. elevator frame and is held in the desired position by a strut 24 pivotally connected to the conveyor section at 25, and which has its lower end provided with a series of notches or teeth 26 which are adapted to engage a link 27 whereby the strut Will beheld in position to secure the adjustable conveyor in position to discharge hay from the elevator'at the desired elevation onto the wagon. v

A pair of alternating rake. carriers 28 and 29 is provided with a seriesofrake bars 30..

The lower ends of the rake bars 80 of the carrierv 28are cross-connected by an arch bar 31, by means of the brackets '32 and I 4 braces 33. Rake bars 30 of the carrier 29 are secured together by a bar 34: by means of hangers 35 and forward and rearward braces 36 and 37. The rake bars 30 are provided with a series of teeth 30 and pivoted rear teeth 31. V

In the operation of the hay loader in.

which the reciprocating rakes are used, a

long substantiafly horizontal and rectilinear l on to the wagons.

forward stroke of the rakinginember and a rapid upward stroke at the forward end of the horizontal movement is desirable in order to gather the hay and elevate the same this merenient i impar do t e. ra e e riers bypitmans, the ends of which are connected to rotate concentrically with the wheel axle of the loader, while the other ends of the pitmans are connected to the rake carrier. These pitmans are curved and are guided in their movement by rollers fixed to the'side of the leader in a 'rnanner that as the pitmans are reciprocated the movement is translatedto the rake carriers so that during a portion ofthe travel of the leader the series of rakes will sweep the ground clean and elevate the hay to l the elevator bottom.

ene to the arch-bar 51' and attheir are prodisposed noai ends of the an axle 1-2 vided with a pair ot oppositely cranks 38 and 39 for driving the rakes. The

cranks are preferably formed integrally with the axle and are connected to the rake carriers: by the curved pitmans 4-1 and 4-2. The pit-man 4111's pivotallyconnectedat 43 to-the carrier 29 thru the bearing lfJrac-k-et 44 fixed to the outside rake bar 30. The pitman 4:2 pivotally connectedfat 4:5 to

the arch bar 31 of the carrier 28. A pair frame by straos sit-ties shown in. Fi '5.

it will he noted that as thesepcur-ved lpitmans are reciprocated over therollers: or

guides that the desiredrectilinear horizontal movement is imparted to the rake carriers i n a manner to gatl'ier and elevate the hay from. the ground to the hayrack. As this movement is imparted to the lower ends of the ratio bar the upper ends of these barsare supported in a manner, to permit a tree reciprocation by a substantially U h aped fix te each bar 30 and s. loosely embracing the longitudinally extending rods secured at their forward rear:- warcend the arch ban 32;

in order to oyercoine the erkingand: 11515 eyenness oi operation in this type. of recipe" rocating rake loadcig I have provided a balancing device which is dentical? ton both s des of: the loader and includes. a bracket 53 secured to the forward encl'ott the pitman il ad iacent the crank 38; Thehraeket 53 is prev-idea with vertiealty disposed; Wall's i i-tor the purpose of guiding in ayenti'ca] In the present invention center position;

carrier 29v assume their rear-most position that theadd'ed weight of these members is to the rear of the fulcrum or rollers s, and

also in this position that the link 55 has forcedthespian-gs 58 to the pos tion shownin the upper dotted lines in Fig. 1, in

which position the springs have been fur ther extended in a manner to assist the traction power to overcome; the weight to the rear of the fulcrum orroller 46 in 'movingthe carrier and rakes over their dead Then when the crank 38 has traveled 180 from the position-just described, the pitman 42' andLcarri-er 28 will assume their rear-1n..- .pesitien with the additional"weigh-t oi? the carrier 28 to the rear of the fulcrum or rollers 456; in this position the link 55 and springs 58 will take the position shown in the lower dotted lines in Fig. 1, wliere the springs 58' have n againbeen further attend-ed i-n-a manner to eqi-ralise the wei'g of the carrier to the rear of the fulcrum or rol' lier'and to, assistthe carrier 28 and itsra-kes oyei thei-r dead center position.

From theabove description it will; be seen that asimpleand efficient equalizing or balancing mechanism has been provided to overcome the jerking and unevenness of 0} er: tion due to the reciprocation of ra-lte carriers And also that a simple and e'fiicient construction of a reciprocating hay leader has been provided with a minimum number (vi-"movable parts;

While I have described but one embodiment which my invention may assmne it is to he understood that modification may he made without depa-rtingii'rom the. spirit and seope'oi" the appended claims;
